R Functions implementing UCR Matrix Profile Algorithm (http://www.cs.ucr.edu/~eamonn/MatrixProfile.html).

This package allows you to use the Matrix Profile concept as a toolkit.

This package provides:

• Algorithms to build a Matrix Profile: STAMP, STOMP, SCRIMP++, SIMPLE and MSTOMP.
• Algorithms for MOTIF search for Unidimensional and Multidimensional Matrix Profiles.
• Algorithm for Chains search for Unidimensional Matrix Profile.
• Algorithms for Semantic Segmentation (FLUSS) and Weakly Labeled data (SDTS).
• Algorithm for Salient Subsections detection allowing MDS plotting.
• Basic plotting for all outputs generated here.
• Sequencial workflow, see below.

# Basic workflow:
matrix <- tsmp(data, window_size = 30) %>% find_motif(n_motifs = 3) %>% plot()

# SDTS still have a unique way to work:
model <- sdts_train(data, labels, windows)
result <- sdts_predict(model, data, round(mean(windows)))

Please refer to the User Manual for more details.

Please be welcome to suggest improvements.

data <- cumsum(sample(c(-1, 1), 40000, TRUE))
